FOOTNOTE: 1 Hazardous waste number.
FOOTNOTE: 2 Chemical abstracts service number.
FOOTNOTE: 3 Quantitation limit is greater than the calculated regulatory level. The quantitation limit therefore becomes the regulatory level.
FOOTNOTE: 4 If o-, m-, and p-Cresol concentrations cannot be differentiated, the total cresol (D026) concentration is used. The regulatory level of total cresol is 200 mg/l.
